No idea on country of origin or timeframe, but notice that this is a "winged wheel"; so in all likelihood, these are not pilot's wings, but railway-related.
..I thought centre looked more like a camera ...and resembled French wings ...
Looks vaguely Dutch? I'm stumped though. the black wool backing does not suggest air forces to me.
.....a lot of wings have black backing....this one though has stumped me ......as it resembles a number of wings, ..they are full size breast wings about 3" !!
